There appears to be contradictory information in the 12000XP manual around what type of external RSD E-Stop disconnect switch to use, so I'm looking for clarification and possible a manual update.
On Page 30, section 9.1 EXTERNAL RSD, the first bullet point states:
- "The external switch must have normally open contact type for emergency shutdown."
Later down the page in the wiring diagram, next to the picture of a yellow/red E-Stop button, it states:
- "Provide 12VDC/1.5A output when inverter is on. Cut off supply 12VDC when Emergency stop switch is ON and RSD is shorted"
So which one is it?
- If the text in the bullet point is correct, this would imply a Normally Open (NO) switch is required. Where the circuit is open (disconnected) in the default state. And when you press the button the circuit is closed (connected), allowing current to flow.
- If the text in the picture is correct, this would imply a Normally Closed (NC) switch is required. Where the circuit is closed (connected) in the default state. And when you press the button, the circuit is "cut off" or opened (disconnected), stopping the current flow.
